With the
frequency scanning of the Sun preserved, it is intended to equip each antenna with a multiwave feeder and a system of
synthesizers to covert the signal frequency at the new frequencies to the SSRT’s working frequency in
order to make use of the existing wideband system of signal collection, and to
temporally separate the recording of
data at different frequencies [5-7] (Fig. 5). Elements from this version are already being worked out by co-participants.
However, this version does not provide radio images with the necessary temporal resolution (on the
order of 1 s). Already at the present
time the SSRT observations are impossible to use in cooperative programs such as HIGH CADENCE IMAGING CAMPAIGN: MEDOC. Therefore,
design solutions are under development
for switching over from many-frequency scanning to aperture synthesis. Preliminary results show
that this approach is realistic at present, as there is no need to develop an expensive correlator, and
with the present level of computer
technology, its function can be performed by a sufficiently powerful processor. In this case it will be possible to map a full
solar disk at intervals of about 1 s. Added
expenses will be incurred by the use of fiber-optic communication lines via antennas, switching elements, and by the purchase of the
processor.
Consequently, the use of parallel aperture synthesis is more promising because to solve the above-mentioned problems requires
obtaining solar radio images at different wave lengths with sufficiently high temporal
resolution. It is obvious that this can be realized only through the use of parallel aperture
synthesis.
